Fig. 1. Fig. 3 is a transverse sectional view on the line y y, Fig. l.Fig. 4. is a transverse sectional view on the line e z, Fig. I. Fig. 5is a perspective detail view.

Referring to the drawings, A designates the sleepers on which the railsare laid in the usual manner.

B B2 designate the rails forming the main track, and G C2 are the railsforming the side track. These rails all terminate at the switch, asshown, and the rail G ofthe side track crosses the rail B2 of the maintrack, a suitable frog, D, being arranged at the junction, andguardrails E and F being arranged in conjunction with the rails B andC3,this arrangement being mainly as is usual in this class of devices.

G G2 designate the rails that form the continuation of the main track atthe other side of the switch.

The switch in the present instance comprises four rails, Q U G3 D3,which have their ends adjoining the ends -of the railsB B2 and C G3,seated in dovetailed recesses H in a transverse sliding block or chair,I, that is adapted to slide between two guide sleepers or blocks, J J,by operation of alever, K, that is pivoted to the ends of the said chairand fulcrumed on a standard, L, or in `any other suitable manner. blockor chair I will be carried to cause the rails of the switch to registerwith the rails of the main track and side tracks. The ends of theswitch-rails are pivoted, as at M, in the recesses IFI, and the latterare beveled from the By operating this lever the center, as shown at N,topermit slight lateral play of the ends of the rails on.- their pivots.Corresponding chairs or blocks are arranged to receive the rails of theswitches at intervals along the length of said rails, these chairs beingdesignated bythe letters O.O3, being provided with the recesses andpivot-pins, and being carried by the rails between guide sleepers orblocks I? P, all as shown.

The four rails of the switch are arranged as follows:

Q is a straight rail that is pivoted at its end adjoining the rail G3 toal sleeper, A, by means of a pivot-pin, R, and is formed with a bevelednotch, S, in its inner side and at this end, said notch forming ashoulder, T.

U is the next rail,which is tapered at its end, as shown at V, to t thebeveled recess or notch S, and have its end come against the shoulder T,and the top edge of the rail at this tapered end V is cut down, as shownat W', to admit oi' the flange of a wheel passing from rail Q, by saidrail U, to rail G2. The railU is preferably connected with rail Q by abolt, X, working through periorations in the rails and against thetension of a coiled spring, Z. This provides a safe joint, which wouldgive77 should the flange ofthe wheel become wedged between the saidrails.

A3 is a heavy plate, that is bolted to or is integral with the taperedend of rail U and projects from the inner side thereof. This plate istapered at both ends, B3 B3, and is provided with a groove, C3, toreceive the flange of the wheels in passing from rails Q or U to railG2.

D3 is a rail pivoted to the sleeper A by a pivot-pin, E3, at the endadjoining the rail G. To this end of rail D3 is connected the beveledend F3 of a rail, G3, by means of a bolt, H3, passing throughperforations I3' I3` in the rails and working against a coiled spring,J3, so that the Iianges of the wheels can pass between rails D3 and G3when passing from rail D3 torail G.

K3 is a guard-rail, that is arranged inside the joint between the railsG and D3, and there is a block, L3, arranged under the rail G3, at itsjoint with the rail D3, the block being provided with a wide dovetailedrecess, M3, to retain the rail G3.

In ease of two side tracks, as indicated by IOO dotted lines, Fig. l ofthe drawings, two extrarails can be embodied in the switch in theposition shown inl dotted lines.

rlhe operation and advantages ot' niy invention will be readilyunderstood and appreciated. By operating the switch-lever the rails ofthe switch can be carried to canse rail Q to register with rail C2, raillf with rail B2, rail G3 with rail C, and rail D" with rail ll, when theniain track will be closed to trains passing Ytroni the rails G and Gf,so that the trains going this way will be switched onto the siding',while the switch will be open to any trains coming 'roin an oppositedirection, either i'roin the siding or inain track. Thus we have aclosed niain track and an open siding, which will obviate liability toaccident.

l. elaini as my inventionl. The combination ot' the niain track andsidings, the continuation olVl the niain track, the rails Q and D ol'the switch, pivoted at their ends adjoining the continuation ol' theniain track, the rail T, having one end connected to the rail Q and entdown at W", the bleek or plate A, having the groove Cl, the rail G2,connected to the pivoted end of raill` `I @einem by spring inechanisin,and the sliding blocks or chairs for carrying` the rails of the switchand retaining the1n in position, substantially as and for the purposeset forth.

2. The combination, with the inain track and sidings, of the switch,comprising the rail Q, pivoted at l?, and i'ornied with the bevelednotch S, the rail U, tapered at its end V to correspond to said notch S,and having this tapered end cnt down at W, devices securing these railstogether, the rail D", pivoted at l, the rail G, havingthe beveled endF, the spring-actuated bolt H, for securing these rails together, theplate A", having the groove C, and the sliding blocks having therecesses that receive the ends ot' the rails of the switch to operateand retain the saine in position, suhstantially as and i'or the purposeset forth.

In testimony that I claiin the foregoing as niy own I have hereto allxedmy signature in presence of two witnesses.
